...Paris last year the Curie-Joliots bombarded a piece of lithium with alpha particles, produced neutrons and boron atoms. The scientific world at that time was engrossed with neutrons whose existence Cambridge University atomic physicists had just discovered (TIME, March 7, 1932). The significance of the boron atoms in the Curie-Joliot experiment attracted less attention until last week Dr. Kenneth T. Bainbridge, who weighs atoms at Bartol Research Foundation laboratories in Swarthmore, Pa., presented an interpretation...
...fact that boron atoms and neutrons resulted when alpha particles struck lithium atoms confirms the Einstein Formula, Dr. Bainbridge declared. The Einstein Formula which Dr. Albert Einstein reached through recondite logic, looks simple: Mc² equals E.* It simply demonstrates that mass and energy are interchangeable, that heat can bundle itself into a lump of coal as well as a lump of coal can dissipate into heat...
...almost seven (reasoned Dr. Bainbridge in effect). An alpha particle has an atomic weight which may be called four. If they merged during the Curie-Joliot bombardment, their combined weight was almost eleven. If the alpha particle and lithium atom did merge, they at once split into a boron atom and a neutron, whose combined weights totaled infinitesimally more than the combined weights of the lithium atom and alpha particle...
...cosmic construction (Millikan theory) or cosmic disintegration (Jeans theory). They may be the neutrons which Dr. James Chadwick of Cambridge University found bombarded out of beryllium (TIME, March 7) and which Dr. H. C. Webster of the University of Bristol last week reported that he had knocked from boron and fluorine...
...noteworthy that neutrons have been recognized as coming from elements which are the lightest of their groups in the Periodic System. Beryllium is the lightest of the earth alkali group (beryllium, magnesium, calcium, strontium, barium, radium). Boron is lightest of the earth metals (boron, aluminum, scandium, yttrium, lanthanum, actinium). Fluorine is lightest of the halogens (fluorine, chlorine, bromine, iodine and, newly recognized, alabamine...
